Clearblue Advanced Digital Ovulation - Positive, Normal Clearblue ovulation kit from Doc - Negative

Hi, my cycle is of 28 days. I've been monitoring my cycle for months now.

During my Nov cycle as I was going thru some fertility treatment, I was asked by my doc to monitor my ovulation. I was given clearblue ovulation kit (which only shows lines when LH surge is detected). When I detected two lines with clearblue ovulation kit, I also tried using other brand of ovulation kit to test out. It showed two lines too (positive). And when I went to the doctor on the third day, the doctor confirm that I've ovulated.

In Dec cycle, I started to use clearblue advanced digital ovulation test (as its suppose to identify 2 extra days compared to the other ovulation kits) , my cycle started the same day as my Nov and Oct cycle. So I was thinking that I should be at peak somewhere near the same time which has always been around day 14. Initially I tested on day 10 itwas low fertile and suddenly at peak (frozen smile) two days later on my day 12 without the high fertile indication which I can understand as different women get different result.
But as I was in doubt as after few months of monitoring, my fertile day is on day 12 instead of 14, I used the clearblue ovulation which was given by my doctor (which will only show lines) to test, it showed negative (only 1 line showed). I also used another brand, it also showed negative. 2 days later on my day 14 I tried using clearblue advanced digital ovulation kit it showed low fertile, whereas the clearblue test kit from my doc and another brand showed positive instead.

I've been very clear on my fertile and ovulation timing, but now I'm confused after using the advanced digital ovulation test.

I would appreciate if you could answer my doubts here as it's inconvenient for me to call USA as I'm from Singapore.

We would be happy to help,
Siti.  Unlike other ovulation tests which only monitor for the LH surge, Clearblue Advanced Digital Ovulation Tests track the changes in two key fertility hormones, estrogen and LH.  If the necessary changes in estrogen are detected, the holder will display high fertility in the form of a flashing smiley, and if the necessary changes in LH are detected, the holder will display peak fertility in the form of a solid smiley.

It’s not uncommon for the holder to change from low fertility to peak fertility without displaying high fertility.  This can happen if the hormone changes naturally occur close together, if your estrogen level is not high enough to be detected by the test, or if tests are missed or not performed correctly.  Since you mentioned the smiley was "frozen,” please keep in mind that peak fertility will remain on the screen for 48 hours and indicates that you’re at your most fertile time.  Have intercourse at any time during these 48 hours to maximize your chance of conceiving.  Once peak fertility has been detected, it’s not necessary to perform any more tests this cycle, and your holder and any remaining test sticks can be saved for a future cycle.

We understand your concern with your results.  It’s important to begin testing on the correct day of your cycle according to the chart in each of the instruction leaflets.  Since your cycle length is 28 days, you should begin testing with Clearblue Advanced Digital Ovulation Tests on day 8 of your cycle and with Clearblue Ovulation Tests on day 11 of your cycle.  If you began testing too late in your cycle, this could cause unexpected results.  Other factors which can cause misleading results include fertility drugs/treatments, a recent pregnancy, menopause, or polycystic ovarian syndrome.  You mentioned taking fertility treatments in November, it’s important to note that fertility drugs containing LH or hCG can affect your results.  Fertility treatments such as clomiphene citrate may cause misleading high fertility results but should not affect peak fertility results.  Clomiphene citrate can also affect the length of your cycle, thus affecting when you should be testing. 

We hope this is helpful and wish you the best as you continue to try to conceive!
